Tables, Naming Problem

Is there a good way to name tables that are used as lookup tables? If you have a table for movies and you think that a movie can be in more than one genre. Then you will have tables like the following.

a table for movies, table 1
id name ...
1 Scarface

a table for the movie genres, table 2
id name ...
1 action
2 mafia

a table that links the genres to the movies, table 3
id table 1 id table 2 id
1 1 1
2 1 2

Table 1 is no problem. I name it movie.
Table 2 is the genres. I name it movie_genres.
Table 3 specifies the genres for a specific movie so I name it movie_genres. Duh, already taken.

This is just an example and perhaps not the best. What should I call my to genre tables?
